To (rifle/2 0727, it Hwy concern:

- Be it known that we, CHARLES MCCARTHY andlirttnor M. PHEXICE, citizensof the United States, residing at Columbus, in the county ofFranklin andState of Ohio, have inventedmertainnew and useful Improvements inVehicle-Tire Tools, of. which the following is aispecification.

Our invention relates to a new and useful vehicle-tire tool.

The object of the invention is to provide a a simple tool of superiorconstruction arranged so as to be engaged'with the vehicle-wheel to givegreatl g SO that the casing of a tire may be readily disengaged from the.rim with comparatively little exertion.

Another feature resides in so constructing the tool that-it maybeadvantageously em-' the invention consists of the novel details ofconstruction and operation, a preferable ernbodirnentof which isdescribed in the specification and illustrated in the accompanyingrawings, wherein- Figure 1 is a crosssectional view of a wheel-rim and atire-casing, showing our improved tool in position and. having its endin 'engagement'with the tire-casing, w ich has been'pressed inward andout of the mm. Fig.

2 is a cross-sectional view showing the tool in elevation and pressingback the casing, so as to allow the lug to be inserted during theoperation of placing the tire in position, the hook being removed; Fig.3 is a partial inner side elevation of the outer end of the tool, andFig. 4 is a plan view of the hook.

In the drawings the numeral 1 designates a lever-arm which is formed atits lower or long end with a suitable handle 2, it being understood thatthe handle may either be formed integral with the said lever-arm orseparately thereof and suitably secured thereto. The le-. yer-arm 1 hasthe general form toward its outer end of an ogee curve or is formed atits outer end with what we have termed a Specification of LettersPatent.

rim and engage with the tire.- At its extreme end the arm is formed;with azconcaved and rounded plate 4, preferablyformed:inte

gral on the arm. This plateprovides an elon: gated and comparativelybroad surface which when brought intov contact wi-thi the tire will notdeface or injure the same. Pref erably at the inner section of thecurved portion 3 and the lever-arm we provide an aper-' ture or opening5, adapted to receive-a screwbolt 6, which passes through thefurcations7 of the bifurcated end of a hook 8. The leverarm being received in thebifurcated ends, the furcations will stand'on each side thereof, and thehook will thus be pivotally supported by The hook is curved or offset,so that when it is engaged with the spoke 9 the levenarm will only standat a slight distance to one side, thus bringing the pressure when thelower end of the hook is swung outwar into contact with the tire-casingjust above the clencher-rim. The operator grasping the handle 2. and bypulling the same outward the portion 3 or gooseneck is forced inward,which pushes the heel of the tire inward and out of engagement with theclencher-rim,

thereby allowing the holding tool, which forms the subject-matter of aseparate application, filed March 18, 1905, and bearing Serial No.250,813, to be engaged under the tire and force the same upward in theusual manner. It will be apparent thatby employing the hook 8 andengaging the same above the spoke 9 great leverage is had and acomparatively light force exerted on the handle end of the lever-arm 1will cause the short end or curved portion 3 to be forced against thetirecasing with sufficient force to press the said casing out of theclencher-rim.

In utilizing the tool when placing a new casing on the rim or put-tingthe old casing back, inplace the screw-bolt 6 is 'disenga ed from thethreaded aperture 5 and the hoo 8 removed. One side of the tire havinbeen placed in the clencher-rim in the usua manner, the gooseneck isinserted in the tire so as to cause the concaved surface of the plate 4to rest on the inner surface of the tire over the rim. Thenby moving thelever arm upward to the position indicated in Fig. 2the casing will ingsfrom clencher-rims, comprising a lever placed on the lever-arm and thetool emact details of construction and operation herereadil inserted orremoved. After lugs have een inserted the hook 8 may ag he ployed toforce the free end of the casing inward, so that it will readily springinto the clencher-rim when the pressure'is relieved.

Considerable trouble has heretofore been ex- Eerienced in removing andreplacing the lugs; ut it is apparent that by employing the tool hereindescribed the lugs may not only be expeditiously removed or repl ced,but free ac cess thereto will be had thus enabling the operator toinspecthis work as he roceed's.

We donot wish tolimit ours ves to the enin described, as we may makevarious changes Wholly within the scope of our claims Without departingfrom the spiritof the invention.

Having now fully described our invention, what we-claim, and desire 176secure by Letters, Patent, is

1. A tool for removing pneumatic-tire cas- I are, at a,

face, a handle provided at the other end 0 saidlever and a hookpivotally secured to lever intermediate its ends; said hook lyingm thelever interr'nediate its ends and extending transversely thereto.

In testimony whereof we afiir our signatures in presence of twowitnesses.
